Heya guys (and gals), I know that the best route to go is to use an A&K/CA/MAG box magazine, however, I was wondering if anyone has had any luck with using any other kind of mag in their SAW. While I could use a high cap M4/M16 mag with velcro/duct tape/painters tape to fill the gaps, that just isn't feasible for me right now. I have looked at using the Echo 1 'fatty' mag and the new Angel Custom Firestorm, I just want to hear anyone elses experiences with another mag type. Has anyone found a mag that is unusually fatter than the standard stanag style, magpul, pmag, C-Mag, etc. etc.? Thanks in advance.
